Born in Amsterdam, the Netherlands, Henk Barendregt (1947) enjoyed (1952-1965) a form of education, that was pioneered at Via dei Marsi 58, Roma, by Maria Montessori. He is professor of Foundations of Mathematics and Computer Science at Radboud University, Nijmegen, The Netherlands. In California he studied from 1972 until 1979 Zen meditation under Kobun Chino Roshi (1938-2002); later in the Netherlands from 1979 until 2006 Vipassana meditation under Phra Mettavihari (1942-2007). Barendregt teaches Vipassana since 2001. In 2006 he was qualified by Phra Mettavihari to direct Vipassana retreats in the style of Mahasi Sayadaw. With colleagues at Nijmegen University Barendregt studies the physiological basis of vipassana meditation and its clinical application of Mindfulness interventions. Inspired by vipassana meditation Barendregt joins at present Prof. Antonino Raffone at Sapienza University, Roma, designing computational models of the mind.
